8. Professional FAQ: Large Cast Iron Roaster Technical Clarifications

Q1: What alloy grade is used in the HAPI large cast iron roaster?

A1: The pan uses high-purity gray cast iron (ISO 185 grade EN-GJL-250). Each batch is spectrographically tested to guarantee >97% Fe and

Q2: What is the typical wall thickness and why does it matter?

A2: The standard wall thickness is 4.8–6.5 mm. This optimizes energy retention (thermal lag) while avoiding excessive weight and minimizing hot spots—key for uniform roasting.

Q3: How is the enamel applied and what benefits does it offer?

A3: Enamel is electrostatically sprayed in two layers and then kiln-baked at up to 860°C. It provides chemical resistance (no leaching), easy-to-clean surfaces, and vibrant color options compliant to LFGB & FDA food safety standards.

Q4: What certifications does HAPI’s roaster carry?

A4: Certifications include ISO 9001:2015 (quality management), LFGB and FDA (food grade), and EN 12983 (safety of cookware handles/lids).

Q5: Are there special installation or usage requirements for industrial sectors?

A5: No installation required. For industrial applications, recommended cyclical pre-treatments and thermal shock tests are conducted as per ASTM G154 or client specification.

Q6: Can the large cast iron roasting pan be customized?

A6: Yes. All parameters—dimension, logo, color (RAL/Pantone), and even handle style—can be fully customized. Private mold development is offered for large orders.

Q7: What testing is performed before shipment?

A7: Each batch undergoes dimensional inspection, salt spray test (ASTM B117 ≥500h), enamel adhesion pull test (>30 N/mm²), and thermal cycling evaluation (≥800 cycles at 400°C).
